Abstract

A LED (4), located within a recess in a casing (2), emits light along an optical axis (2A). A primary focusing lens (6) and a secondary focusing lens (8) are set into the casing and located along the optical axis to focus the light emitted by the LED. The curved surface of the recess curves toward the primary focusing lens.
